This $800,051 federal Project Grant awarded by the U.S. Environmental Protection Agency's Science to Achieve Results (STAR) Research Program (CFDA 66.509) aims to examine baseline levels and bioavailability of per- and polyfluoroalkyl substances (PFAS) in typical resources for urban farming and gardening. The project will: (1) quantify the impact of soil, nutrient amendments, and irrigation water on PFAS uptake in crops grown in raised beds; (2) sample local freshwater and rainwater for PFAS baselines; (3) measure PFAS in edible plant parts and soils after urban crop harvests; and (4) assess other vital plant functions. This 3-year project, starting September 2024, is expected to deliver annual and final progress reports as well as peer-reviewed publications to improve understanding of PFAS bioavailability in urban-grown crops. The intended beneficiaries are urban community gardeners in Philadelphia and across the country.
